Just talked to Jerry. As of 10 a.m. EDT, he was about 5 miles away from St. Francis, a checkpoint at 511 miles. He says he spent about 6 hours at Atwood, and is currently riding with Brent & Beth, a tandem couple from Denver.
Sounds like he is having a fun ride. He said he is on his Mongoose, a geared bike, and is glad he brought it because of the winds they've faced.
